Global Telescope Network is a project that allows individuals or groups to dedicate some portion of their time to analyzing data taken with other people’s telescopes. The Global Telescope Network is a network of small telescopes around the world for the purpose of supporting the science of NASA and ESA high energy astrophysics missions, including XMM-Newton, Swift and GLAST. These missions are designed to study astronomical objects through their emission of x-rays and gamma rays. However, much can be learned by combining observations over a broad range in the electromagnetic spectrum. The GTN has been assembled to make observations in the optical that will compliment the observations done at higher energies by space-borne observatories.

Andromeda I or Andromeda 1 is a dwarf spheroidal galaxy(dSph), is a companion of the great Andromeda Galaxy M31. It´s very dificult to see, even with a good telescope will appear only a small dot. [1][2]

Andromeda I it´s about 2.40 million light-years away in the constellation Andromeda. [1][2][3]

Andromeda I is part of the Local group of galaxies and a satellite galaxy of the Andromeda Galaxy (M31). It is roughly 3.5 degrees south and slightly east of M31, at an estimated projected distance of ~40 kpc or ~150,000 light-years. [1][2][3]

The Boomerang Nebula also called the Bow Tie Nebula and PGC 3074547, is a protoplanetary nebula, in the constellation Centaurus, is the coldest known region in the Universe. [1][2]

Is located 5,000 light-years away from Earth, and is coldest place in the Universe found so far. With a temperature of -272 degrees Celsius, it is only 1 degree warmer than absolute zero (the lowest limit for all temperatures). [1][2]

The Andromeda Galaxy also known asMessier 31, M31, or NGC 224 is a spiral galaxy approximately 2.6 million light-years (2.5×1019 km) from Earth[1] in the Andromeda constellation, that´s where comes its name from. On a moonless night, the Andromeda Galaxy is visible with the naked eye.[1][2]

The Andromeda Galaxy is the nearest spiral galaxy to our galaxy (Milky Way), but not the closest galaxy overall.[1]

The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains our galaxy (Milky Way), the Triangulum Galaxy, and about 30 other smaller galaxies, contains one trillion (1012) stars:[1]at least twice the number of stars in our own galaxy, which is estimated to be 200–400 billion.[1]

Ambartsumian’s Knot is a dwarf elliptical galaxy in the constellation Ursa Major. It is the small blue dot off the bottom of the eliptical NGC3561A.[2]

The entire system is called Arp 105, or “The Guitar”, because of its overall shape. “The Guitar” as an example of new galaxies being formed as ejections from older galaxies.[4][1]

Ambartsumian’s Knot is located at the end of what appears to be a bridge of matter extending from the elliptical galaxy NGC 3561B (R.A. 11h 11m, Dec. +28° 42′). The latter is interacting with the nearby spiral galaxy NGC 3651A giving rise to a number of tidal tails and tidal dwarf galaxies. [2][3][4]

The enormously long tidal tail visible to the left (north) of NGC 3651A in the accompanying photo, Arp 105N, stretches out for 100,000 parsecs (325,000 light-years) from the parent galaxy.[2]

Arp 150 lies close to the center of the rich cluster Abell 1185, which lies about 400 million light-years away. [2]
